Given numbers are 822, 802, 257, 480

The list of prime factors of all numbers are

Prime factors of 822 are 2 x 3 x 137

Prime factors of 802 are 2 x 401

Prime factors of 257 are 257

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 822, 802, 257, 480

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(822, 802) = 329622

GCD(822, 802) = ( 822 x 802 ) / 329622

= 822 / 802

= 822

Step2:

LCM(2, 257) = 514

GCD(2, 257) = ( 2 x 257 ) / 514

= 2 / 257

= 2

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 822, 802, 257, 480 is 1
